I actually paid attention in physics and that is why my comprehension of the basic principles is stronger than many on this message board. I try to deal with one issue at a time rather than race around like polarbear, mixing up one concept with another and getting confused in the process.
radiation near the surface is a poor method of shedding heat because it is dispersed in all directions. therefore convection and latent heat from evaporation do much of the lifting to higher altitudes. at higher altitudes the tops of clouds release that heat through radiation. radiation is the only way for energy to escape the earth.
the complexities are enormous but the bottom line is that highly ordered higher energy sunlight is absorbed by the earth where it is used to power natural systems which in turn return that energy as lower ordered, lower energy IR radiation to space. fully adhering to the second law of thermodynamics. it is obvious by life on earth, wind and ocean currents, etc that entropy can be either increased or decreased along the pathway as long as the final tally is correct.
Neither you and all the other instant forum heat radiation experts realize what kind of nonsense you`ve been writing in here about Spencer`s positive back radiation "energy feedback", pretending you have even the slightest understanding of any of the equations you copied&pasted in here.
That does not necessarily make any of you the same kind of idiot Spencer is...unless you sat through physics lectures like Spencer and still are too dumb to understand any of it after the principles of thermodynamics have been thoroughly explained...
hahaha...but you are...because I`ve explained it to you over and over again and yet just like Spencer and his dumb daughter, the realtor you still think that a black body which radiates a temperature specific frequency profile is the same process as heating a black body to a specific temperature with radiation...
Furthermore heating the CO2 in the air with "black body" radiation, then feeding back the CO2 absorbed IR as "back radiation" to increase the GROUND temperature even more is beyond hahahaha..
